To all whom it may confciem:

Beit known that I, FRANK H. CHASE, a

citizen of the United States, residing at Chi- One'of the principal objects of the inven tion is totprovide a refrigerator which may be quickly and easily positioned Within and removed from the earth, and which shall be g l particularly adapted to the use of campers and others who wish a cooling apparatus which may be moved from place to place and readily positioned for use. y

A A further object of the invention is to provide a refrigerator fof the character de scribed which will be perfectly ventilated at all times, and so constructed that the air within the provision chamber will be changed every time 'articles are put, in or removed therefrom.

Another aim of my invention is to provide a refrigerator of the type described which will be cheap to manufacture, simple of construction, and which will occupy a minimum space whennot in use.

Further aims and advantages of the in-,

vention will be apparent as it is bet-ter understood from the following description which, taken in connection with the accompanying drawings, discloses one preferred embodiment thereof.`

On the drawings :-Figure 1 is a vertical sectional view of a refrigerator made infpursuance of my invention in operative position in the ground; Fig. 2 is an enlarged horizon- 'tal sectional view on the line 2-2 of Fig. 1; Fig. 3 is also an enlarged horizontal sectional View which is'taken on the line 3--3 of Fig. 1, and Fig. 4 is a fragmentary vertical sectional view showing the means connectingihe receptacle-receiving angle-irons to the side members of the frame.

On the drawings, an outer casing or member 10 is formed of a plurality of cylindrical sections 11 which are joined together by' .the interlocking ribs 12 constructed to provide a comparatively smooth surface within the member. The member 10 is provided at with the interior of the member.

its bottom with a closure 13, and atta substantial distance beneath its top with the pipe-receiving sockets 11 communicating In these sockets are 'fastened in suitable manner the outwardly ext-ending pipes 15 provided at their ends with the elbows 16,v into which are secured the upwardly extending pipes 17. The pipes 17 are of sufficient length to extend above the top of the melnber 10 so that when the refrigerator is in use their ends will be disposed a substantial distance above the surface of the ground. Each is provided at its upper extremity with a T 18, through which atmospheric air is admitted to the interior of the member by means of pipes 19, elbows 2O and pipes 19 secured in the elbows. The pipes 19 are preferably disposed downwardly from the elbows 20 to prevent rain-water from entering and lodging in the chamber 10. The Ts 18 are connected by' the U-shaped pipe or solid rod 21, which extends above lthe member a distance somewhat greater than the length of the member. A second hollow 'member 22 closed at its bottom 23 and of substantially less dimensions' than those of the member 10 is provided at itsv top with a downwardly inclined and outwardly disposed tiange 24 extending about its upper peripheral edge. This fiange is of lsutticient width to permit it to extend over` the top of the member 10, supporting the member 22 in proper position and sea-ling the space formed between the two members.

A cover 25 is provided for the member 22 and is preferably .made in t-he form Aof a sheet-metal box formed to fit closely within the member 22 and filled withI asbestos or other suitable non-heat-conducting material 26, the sheet 27 forming the top of the said cover extending beyond the `-sdes of the cover to form an outwardly extending anupon the flange 24 of the member 22, forml ing an vair chamber between the iianges 28 -and 24. To more perfectly seal, this air space, and to effect a more perfect closure for the member 22, Il provide suitable packing 31 upon the, top'bf the flange 24 against which the downwardly turned edge 29 of the flange 28 rests. Through-the center oi the cover in a suitable apertureis rigidly fastened a pipe 32 closed at its ends and provided with apertures 33" and 34, the apertures 34 being dis osed above the cover and y the top of the member via the pipe 32' through' apertures 33'and 34;

To prevent insects, dirt, etc., frmnenter-v `i`ng the member 22, l cover the ends of the pipe 19' and ,the apertures 33, 34 and with gauzez wire or other suitable material 40 adapted to permit the free entrance of air, but to restrain the admission of objec# 'tionable insects or dirt.

Within the-member 22 is suspended'a frame 36 adapted to receive a plurality of receptacles '37 containing the articlesto be kept cool. This frame consists of a stiff strap 38 bent in U-*shape form to which circular supports 39 are fastened at intervals by means of rivets, bolts or other suitable fasteners 41.. The receptacles 37 are preferably circular in form, and of a diameter adapting them to fit easily within the vertical walls 42 of the supports 39, to rest upon and be supported by the horizontal flanges 43 of these supports. The bottoms of all but the lowermost of these receptacles are perforated to permit the free passage of air around the articles carried thereby', and are Shown in the present embodiment as having their bottoms formed -of heavy wire gauze i4. The lowermost receptacle preferably has a solid imperforate bottom which acts, when the frame is lifted or lowered, much as the piston of an air pump, forcing the air within the member 22 out at the top when theframe ascends and out through the apertures 35, up between the walls of the members 10 and 22 and eventually out through the pipes 19 when the frame is lowered. Thus-each time the frame is lifted out of the refrigerator practically a complete change of air the inner chamber 1sl effected. A

The. frame 36 is suspended from the cover ,25, by means of the links 45- and 46, the latter link extending through and being fastened within the pipe 32. A pair of pulleys 47 and a rope 48 connect the upper'end of the link 4`6 with a clevisl49 carried by the Uf shaped pipe 21 at its top, and provide means for raising the cover and the frame withlts receptacles.

At the bottom 'of the'pipe 32 andfimme-l diately below the aperture 33 is secured a cup 52 encircling the pipe, and above the ,cover a similar cup 53 is fastened. Theseh cups are adapted to contaln water or, 1f`desired, poison, and are provided to prevent emmets and other small creeping insects 'from entering the member 22 by working through the gauze or wire 40. Upon the up per end of the pipe 32 is provided a shield 51 to prevent rain from beating in through the aperture 34 and wetting the contents of the refrigerator or flooding the upper cup.

It will here be noted that the present refrigerator includes a casing having inner and outer spaced walls 22 and 10, defining an annular air space which is in communication with the atmosphere through the pipes 15 and 17 and the elbow 20, and-with the interior of' the casing through the opening in the lower part of the inner Wall 22. Moreover the interior of the casing is in direct communication with the atmosphere through the pipe 32 which extends through the cover. The receptacle for containing the food has a slidable fit within the casing and constitutes a plunger to expel air from and draw air into the refrigerator through the two communications with the atmosphere.-

VVhenit is desired to position a 'refrigerator made in pursuance of my invention in -the groiind it is only necessary that a hole of suitable diameter be bored b an earthauger or otherwise formed, su cient earth being removed on opposite,y sides of the hole to receive the pipes l5 and1y17, and the member 10 inserted therein. Into the member 10 may then be lowered themember 22, and the pulleys, cover and frame-work put in place. The whole refrigerator may be easily lifted out of the ground and moved to another locality by uncovering the pipes 15, if earth has been`t positioned thereabove. It is apparent that the U-shaped pipe-21 may be moved around the pipes 15 as a center until the top of the pipe is disposed behind the bottom of the member 10, thereby reducing the compass of the refrigerator 4 materially when it is desired to store the refrigerator or to load it on a Wagon on moving to.ano ther locality. e

It will be manifest that numerous change may be made in the form, construction and arrangement of the parts without departing from the spirit or scope of my invention or sacrificingr any of its advantages, the form h'ereinbefore disclosed being merely one preferred embodlment thereof.
